MACHINE FOR SIZING AND COLORING PAPER AND OTHER FABRICS.

SPECIFICATION forming part of Letters Patent No. 346,894, dated August10, 1886.

Application filed May 14, 1886.

To aZZ whom it may concern:

Be it known that I, HENRY F. CASE, of South Manchester, in the county ofHartford and State of Connecticut, have invented certain new and usefulImprovementsin Machines for Sizing and Coloring Paper and other Fabrics,of which the following is a full, clear, and exact description, wherebyany one skilled in the art can make and use the same.

My invention relates to the class of machines used in saturating orcoating or otherwise treating the body or surface of a sheet or web ofpaper or textile fabricsuch as cotton,linen, or the like-with afinishing, stiffening, waterproofing, coloring, or glazing substance insolution by means of a series of rollers.

The object of my invention is to provide a compact, simple, andcomparatively inexpensive machine for the purpose of thus treating paperand other fabrics, and one that can be readily changed to adapt it toeither sizing, coloring, or printing paper or other fabrics in thinsheets or web.

My invention consists in the combination of two or more main rollers,one or both of which serve as mediums for'applying the solution to thesheet or web of fabric passing between them, the feedrolls, one of whichbears a fixed relation to one of the squeezerolls with reference to themain roller, the squeeze-rolls, and the tank or roll for applying thesolution.

It further consists in the peculiar solutionfeed roll in combinationwith the main rollers, feed and squeeze rolls, and in details of theseveral parts and their combination, as more particularly hereinafterdescribed,and pointed out in the claims.

Referring to the drawings, Figure l is a view in end elevation of amachine embodying my invention, with parts broken away to showconstruction. Fig. 2 is a view in elevation of the opposite end of themachine. Fig. 3 is a View in vertical cross-section of the machine onplane denoted by line as x of Fig. 5. Fig. 4 is a diagram Viewillustrating the operation of the device connecting the upper feed-rolland one of the squeeze-rolls. Fig. 5 is a top or plan view of themachine. Fig. 6 is a front view of the machine, showing the solutionfeedroll not shown in the other views. Fig.

7 is a detail view in longitudinal central section of thesolution-feedroll on enlarged scale.

Fig. 8 is a detail cross sectional view of the roll on plane denoted bythe line y y of Fig. 7. Fig. 9 is a diagram view illustrating the deviceused when a web of fabric is running through the machine.

I In the accompanying drawings, the letter A denotes the frame of themachine, that is preferably of iron cast to shape, and consists of theside parts, a a", joined by the tie-rods III), the lower ends of thesides broadening to form the feet a The side parts are practicallycounterparts of each other, and the main rollers B C have their journalssupported in bearing-blocks d (2, respectively, that are movablevertically in the frame, the ends of the blocks having lips that overlapthe opposite edges of the opening in the frame and hold the blocksagainst lateral displacement. The upper blocks, (Z, that support thejournals of the main roll B, are suspended by the rods 6 from the yokee, and are vertically adj usted by means of the screw-rod 6 that turnsin a threaded socket in the cross-bar a of the side parts and whilerotating freely in the bar 6 through which it passes, and is heldagainst sliding movement therein by collars fast to the screw-rods onboth sides of it. A tank, D, is supported below the lower roller, C, sothat the latter may slip and move in any liquid or solution contained inthe tank. Cn the front part of the frame are mounted the feed-rolls andthe squeezerolls. The shaft or journal of the lower feedroll, f, isborne atits opposite ends in the brackets 99, that are secured to thefront of the side parts of the frame, while the upper feed-roll, f, issupported by the levers h at opposite ends, the levers being pivoted tothe side parts of the frame, so that this upper feed-roll will rest uponthe lower in its normal position. Each of the levers h (there are two ofthem) is pivoted to the side part so as to move in a vertical plane, andit has an arm, h, pivoted to and extending downward from the lever, aslot, h in the arm h and a bolt and nut, 71.", serving to make theconnection adjustable. I11 the lower end of the arms h are formed thebearings for the opposite ends of the shaft or the journals of the uppersqueeze-roll, t, the lever h and arm h being so adjusted that thesqueeze-roll i will be pressed forcibly against the surface of the mainroller C by the weight h" on the outer end of the levers before thefeed-rolls will be in contact. The lower squeeze-roll, i, has itsjournals borne in a slot, 1, in the bracket, the end of the adjusting-screw j being thrust against the journal with a yielding pressureby a weight in the outer end of the lever j in a downwardprojectinglugfrom which the screw jis borne.

The object of this peculiar construction and arrangement of thefeed-roll and connected squeeze-roll is to prevent an undue amount ofthe solution being brought into contact with the paper or other materialthat isbeing treated in the machine. One or both of the main rollers (inthis case the roller 0) is provided with a jacket or cover, 0, ofabsorbent material, as cloth or felt, and these main rollers are soadjusted that their peripheries are nearly in contact, it being ofcourse necessary that the sheet or web of material should meet with somepressure in its passage between the rollers. The function of thesqueeze-rolls i t" is to leave on this absorbent jacket the necessaryamount of the solution, and, except when the upper squeeze-roll, t, isin contact, there would be danger of the transfer of the solution to thetop main roll or an accumulation of it between the rollers on the frontside. It is to prevent this accumulation or transfer of the solutionthat the upper squeeze-roll, t, is held in contact with and operates incombination with the lower squeeze-roll, 11, to express nearly or quiteall of the solution from the cover except when the sheet of material k(see Figs. 3 and 4) is being passed through the machine. When this istaking place, the introduction of the edge of the sheet of materialbetween the feedrolls lifts the upper one, and in so doing withdraws thesqueezeroll 2' from the main roller 0, thus leaving a quantity of thesolution in the cover of the roll, which will be transferred to theunder side of the material It as it passes between the main rollers. Iprefer that these several parts shall be so arranged that the distancefrom the point 1, denoting the point of contact of the surface of therollers B O, to the point of contact 2 of the squeeze-roll i with themain roller 0, shall be equal to the distance from the point 1 to thepoint 3, where the surface of the feed-rolls are in contact. By thisarrangement of the parts the front edge of the sheet of material as itpasses between the main rollers is met by the appropriatelymoistenedcover a, and waste of material It or transfer of the solution to theupper roll prevented. The

main rollers and feedrolls are driven by means of a belt passing aroundthe pulley O, that is fast to the shaft of the lower main roller, whichshaft bears a cog-wheel, C, in mesh with the smaller cogs 0 G the latterbeing borne on the shaft of the feed-roll f. The cog-wheel O is borne ona lever, C, the upper end of which is pivoted on the shaft of thefeed-roll f, while its lower end has a slot, 0'', through which a boltpasses, so that, by means of a nut, the lever may be held with thecog-wheel C in mesh with the cog-wheel G or out of mesh with it. Thisarrangement of the parts will adapt the machine for operation uponsheets of material of varying thicknesses.

In the case of paper, sheets from extreme thinness to the greatestthickness of binders or pressboard may be treated with a solution ofsizing, coloring, waterproofing, or other material used to finish orspecially prepare the paper. In case it is desired to thus treat paperor like material in the web, I find it con-' venient to make use of thedevice shown in the diagram view in Fig. 9 of the drawings. In this casethe long levers M are pivoted one upon each side of the frame A, andproject forward, the shorter arms of the levers taking under thejournals of the top roller, B, and having also bearings in which theroller turns, while on the extreme front end of these levers is borne aguide-roll, n, under which the web is passed before it is grasped by thefeed-rolls The outer end of these levers M is weighted, tocounterbalance the weight of the main roller B, the tension of the web 0being just sufficient to cause the rollers B O to turn in contact withthe web and press upon it; but in case the web should break, the outerends of these levers M will drop, and the upper roller, B, will belifted out of contact with the lower roller.

Instead of putting solution in the tank D or in connectionwith thistank, I make use of a solutionfeed roll, P. The roll is composed of acentral tubular part, 1), that is preferably of the same interiordiameter as the inlet-pipe p and the outlet-pipe p and it has anoutletopening in the wall of this central chamber, 1), of the roll. Onthe outside of this cen tral part, 1), there is provided a cover orpacking, p, of absorbent and porous material, as cloth or felt, andoutside of this is the rotary body part 1), that has a rigid shell, 1),of tubular form fitting closely about the inside packing, and with itswalls imperforate. This shell 1) has an outside jacket or cover, p ofabsorbent and porous material, as cloth, and through these several wallsand covers any coloring, sizing, or other material in solution is forcedunder pressure, and the degree of this pressure is determined andcontrolled by the regulator-valve R on the outlet-pipe from the roll.The central body part of this feed-roll P is preferably fixed againstrotation, and owing to the regularity of the pressure and provision fora constant circulation of the solution through the roll a uniformsaturation of the absorbent covers results, the rotation of the outerbody part aiding in the even distribution of the liquid without thedeposit of any sediment. I have obtained good results in even coloringof thin paper by running it over this feed-roll P and without theintervention of the main or feed rolls, although for some kinds of workI prefer to use it in connection with these latter parts, and arrangedon the frame, as shown in Fig. 6 of 'the drawings. By covering any partof ,the outer surface of this feed-roll P with a cover that isimpermeable in part, and by making the openings through this of somedefinite pattern, it may be reproduced in color on the fabric treated;or certain parts of the width of the sheets or web may be sized,colored, or similarly finished without affecting the rest of thesurface.

I claim as my invention 1. In combination with the main rollers, thefeed-rolls and a solution-feed roll, the latter mounted with itsperiphery in contact with that of one of the main rollers and consistingof a non-rotary tubular center with an outlet in the upper side and aporous cover, and a rotary outside part with a perforated sh ell and aporous and absorbent cover, all substantially as described. 4

2. In combination with the main rollers, the feed-rolls and thesqueeze-rolls, one of the latter being held forcibly against the surfaceof the main roller to which the solution of coloring or sizing materialor the like is applied, and the other squeeze-roll being borne on an armof a lever and held thereby in fixed relation to one of the feed-rollsthat is borne on the lever, whereby an outward movement of this secondsqueeze-roll is obtained by the lifting of the upper feed-roll by theentrance between the feed-rolls of the material to be operated on, allsubstantially as described.

3. In combination, in a device of the within described class forapplying material in solution by means of rollers, the feed-rolls, thesqueeze-rolls and the tank or equivalent device for applying thesolution to one of the main rollers, one of the squeeze-rolls beingborne on an arm of the lever that bears one of the feed-rolls, wherebythe thrusting apart of the feed-rolls causes the squeeze-roll to bewithdrawn from the surface of the main roller bearing the solution, allsubstantially as described.
